Each year, the Commercial Vehicle Safety Alliance (CVSA) conducts International Roadcheck, a three-day enforcement program targeting commercial motor vehicles. This year's International Roadcheck focused on tire safety and increased tire failures on commercial trucks. Recently released results from the event found that tire violations accounted for 18.5% of out-of-service violations. This is an increase over 2015 (13.9%) and 2014 (13.8%).
